Pogo 0.8.1
A new Pogo version has been released. The tarball and an Ubuntu PPA are available at http://launchpad.net/pogo What is Pogo? - Pogo plays your music. Nothing else. It is both fast and easy-to-use. The clear interface uses the screen real-estate very efficiently. Other features include: Fast search on the harddrive and in the playlist, smart album grouping, cover display, desktop notifications and NO music library. Pogo is a fork of Decibel Audio Player and supports most common audio formats. It is written in Python and uses GTK+ and gstreamer. What's new in this version? --- * Support Pillow in addition to PIL. * Disable zeitgeist module to avoid startup errors on Ubuntu 12.10.

trying to get the cvs data parsed.
Sure hope to teach myself python. Maybe I need to look into courses

don't waste time at college (at least not yet) there are many good
tutorials available on the web.
as you are already an experienced programmer Dive into Python would not
be a bad start the official python tutorial is also one not to miss

handling return codes from CTYPES
PY33, Win7, Python Newbie, Not homework:-) I'm trying to use some 'C' DLLs from Python using ctypes and I have a minor issue with the return valuesbut I am new to Python; ctypes and using DLLs so I am at the bottom of so many learning curves, I'm not sure where or how to find my mistake. When I call the DLL, I am expecting a return of 1 (success) or a negative number (one of a set of error conditions)the return value is specified as 'short' in the DLL call specification - short InitScanLib (const char * szLicense). What I get back is either a 1 or something like 65535. This implies that I am receiving the expected value (-1) but 'something' is being lost in the translation. The code is asper the snippet below: from ctypes import * sLib = cdll.slib lic_key = c_char_p(asdfghjkl.encode(encoding='utf_8', errors='strict')) initResult = sLib.InitScanLib(lic_key.value) print(InitScanLib Result: , initResult) InitScanLib Result: 65535 I've tried declaring initResult as c_short by: inserting... initResult = c_short(0) ... before the call to sLib.InitScanLib but I still get the same response (65535). Interactively, I can see ... c_short(65535) c_short(-1) c_short(-1) c_short(-1) It's not a critical issue because I only want the return value to lookupa textual error message but I do want to understand what's going on.

That's nearly all of them. stdin is short for standard input. Likewise for standard output and standard error. When you give the Python command: print Hello World the string Hello World is written to stdout, which then displays it in the console. stderr is similar, except that it is used for error messages. And stdin is used for input, rather than output. So, in Python, I can do this: py import sys py sys.stdout.write(Hello world\n) Hello world But of course normally you would just use print. Using sys.stdout, sys.stdin and sys.stderr in Python is usually considered moderately advanced. Beginners do not usually need to care about them. These three special files do *not* live on the disk. There is no disk file called stdout unless you create one yourself, and if you do, it won't be special, it will just be an ordinary file with the name stdout. These standard files are used in Unix and Linux, and less so in Windows, for console applications. For example, under Linux I might write this command: [steve@ando ~]$ touch foo [steve@ando ~]$ ls foo foo The output of the `ls` command is written to stdout, which displays it on the console. But I can *redirect* that output to a real file on disk: [steve@ando ~]$ ls foo /tmp/a [steve@ando ~]$ cat /tmp/a foo Errors don't go to stdout, they go to stderr: [steve@ando ~]$ ls bar /tmp/a ls: bar: No such file or directory Because there is no file called bar, the `ls` command writes an error message to stderr. Even though I am redirecting stdout, I am not touching stderr, so it prints to the console. Of course there is a way to redirect stderr as well: [steve@ando ~]$ ls bar 2 /tmp/a [steve@ando ~]$ cat /tmp/a ls: bar: No such file or directory Similarly, you can redirect stdin, or you can use a pipe | to turn the output of one command into the input of another command. This is mostly useful when using something like command.com in Windows, not so common in Python. -- Steven -- http://mail.python.org/mailman/listinfo/python-list

I am stumped!
Here is your code with the irrelevancy stripped away:
function = raw_input(Type in a function:)
#start math loop
if function == math:
#math code
if function == random number:
#random code
if function == games:
#games code
if function == help:
#help code
else:
print (Not a valid function)
Say you enter 'math'. It passes the first condition, so runs the math
code.
It then fails on the next 3 conditions, the last of which has an else,
so if you type _anything_ other than 'help', you'll see Not a valid
function.
Easy answer, use `elif` (else if) instead of else for the subsequent
tests:
if function == math:
#math code
elif function == random number:
#random code
elif function == games:
#games code
elif function == help:
#help code
else:
print (Not a valid function)
Better answer: read up on real functions, and look into dictionary
dispatch:
def f_math():
#math code
def f_random_number():
#random code
etc
function_dispatcher = {
'math': f_math,
'random number': f_random_number,
etc
}
while cmd == 0:
function_name = raw_input(Type in a function:)
if function_name in function_dispatcher:
function_dispatcher[function_name]()
else:
print(Not a valid function)
To have your functions break out of the loop, use a `global` variable
or pass a context object into each function to allow them to set
`cmd`.
Thank you, that solved my problem. Sorry for my posts, i am a noob and this is

RE: Thorough Python 2.7.3 Windows Build Documentation?
Hello again Python programmers, Final update on my Python 2.7.3 build issues. After much insanity I finally used a process sniffer when running Python and tracked down that because of a path environment variable and the stupidity of Microsoft, Windows was loading another python27.dll rather than the one in the directory with the python.exe that I built, thus rendering my former tests useless. Sorting this out using the .exe.local trick, I was able to re-test everything and come to reliable conclusions. Based on performance results, it is without a doubt in my mind that the Python 2.7.3 precompiled binaries in the MSI are a PGO build. I can now build my own binaries with the same performance as the released precompiled binaries. And on my machine at least, these PGO built binaries do perform 30-36% faster than a normal release build. Useful information if you're doing your own Python builds. I'd still like to see Python start including some thorough build documentation on each release, but I'm certainly not going to be holding my breath on that. ;) Cheers.

Well, for what it's worth, I've literally moved from coast to coast and from my experience, that really depends entirely on what kind of programming you want to do. Nevada has lots of jobs for casino-style gaming software development. Texas has a lot of industrial programming for oil rigs. Washington (state) has a lot of Microsoft-related jobs. Portland, Oregon has a lot of Intel-related jobs. Etc. (Pennsylvania just kind of sucked.) In most cases it's about what major business is in the area. So I'd say if you're not looking to be near your family or anything non-work related, then just ask yourself what you want to do, look up who does it best and where their main offices are located, and then apply for jobs there. Even if you don't get the dream job on the get-go, just getting a job that helps you move into the area makes it that much easier to continue applying for your dream job over the years. So you say that you're currently developing Android apps. Google is Android, so I'd suggest looking more around the Mountain View, CA area. (I wouldn't count on a Python-specific career anywhere though. Those kinds of jobs are ones that you have to chase to the oddest ends of the Earth because they're so rare.) Or, if you're just happy being a general programmer or switching things up a lot, then aim for the more heavily populated areas like Silicon Valley and prepare to be chewed up and spat out by random companies while you grow in experience. Just make sure to look into the cost of living in and around the area that you want to move to, keeping various forms of commuting in mind, so that you can plan for how you'll pay the rent once you find a job you like. ;) Fortunately, most major metro areas have good forms of public transportation. (Maybe not enjoyable, but dependable and affordable at least.) That, and if you have any allergies or medical conditions, keep in mind the area. Portland, OR was a lovely place to be my first year there, but my second spring there the pollen counts shot through the roof so I had to leave after a really bad bout of bronchitis. So if you have any health issues, research the area well. Even a whole year of living there isn't always enough to prove the area safe. And good luck!

Why does it fail to load it? Python can have access to ANY filesystempath , no matter from what folder counter.py script runs from. Correct? No I can't because counter.py doesn't load the image. The browser does. If the image fails to load it is because the apache web server cannot find it. In other words your image src url is bad. It has nothing to do with python. Python is only spitting out html code. That's it. Image loading is done by apache on behalf of a request from the web browser. Since the url is a direct url to a file, there is no CGI that runs. I understand that you have a difficulty understanding the relationship between the browser, the web server, and the cgi script. The process goes like this: - browser requests the url, which happens to be the CGI script, counter.py. - web server runs counter.py returns html code to the browser. - browser parses html code, renders it, and requests any images that the html code references. - Web server tries to locate the image based on its own rules and config, and serves it if possible, otherwise, returns error 404. So you simply have the image url wrong. apache is not mapping /data to where you think it is. You have to either fix this in apache's configs, or determine where the image really is in apache's url space, and change the cgi to output the correct html.

serpent, a serializer based around ast.literal_eval
Hi, I've been toying a bit with ast.literal_eval. I've come up with serpent, a serializer based around that. Which means that it takes a Python object tree and turns it into a serialized form that can be safely read back by ast.literal_eval(). Why I wrote serpent and didn't simply use repr()+ast.literal_eval: * it serializes directly to bytes (utf-8 encoded), instead of a string, so it can immediately be saved to a file or sent over a socket * it encodes byte-types as base-64 instead of inefficient escaping notation that repr would use (this does mean you have to base-64 decode these strings manually on the receiving side to get your bytes back) * it contains a few custom serializers for several additional Python types such as uuid, datetime, array and decimal * it tries to serialize unrecognised types as a dict (you can control this with __getstate__ on your own types) * it can create a pretty-printed (indented) output for readability purposes * it works around a few quirks of ast.literal_eval() on the various Python implementations. It works with Python 2.6+ (including 3.x), IronPython 2.7+, Jython 2.7+. Serpent can be downloaded from Pypi: http://pypi.python.org/pypi/serpent A simple example session can be seen here: https://gist.github.com/4588429 I'm considering writing Java and .NET counterparts for this as well so I'll be able to exchange messages between the three.

Sure, the problem isn't here a ctypes issue, but a Python one. When you do the following: initResult = c_short(0) you have bound the name initResult (a string key in a namespace dictionary) to a ctypes c_short object. The name initResult is in no way special, nor is there any type associated with that variable name. The fact that it has been assigned to a c_short *at this moment* does not affect any *future* value assigned to that name. initResult = initScanLib( ... ) Here you have assigned whatever object is the result of initScanLib( ... ) to the name initResult. The old object pointed to by initResult is no longer referenced by that name, so the Python intepreter is free to discard that old object immediately. Thus you have discarded the object you created by reassigning the single reference to it to another object, which leaves it free to be garbage collected (depending on Python implementation that might be instantly or eventually). Python does not have typed *variables*, every variable is a pointer to an object (PyObject *) under the covers. There is nothing in Python like: int i; short j; nothing which makes a variable type-enforcing or constrained. At least, nothing in core Python. In theory you can create a namespace which *does* allow such things, but that's getting pretty involved. Hope that helps, Mike -- Mike C.

Define same in a way that you could do it by hand, and you're halfway towards a programming solution. Maybe it'd be obvious from an analogy. Suppose you're HR for a company with 100 employees, and a strange policy of putting paychecks under the wipers of the employees' windshields. All the employee cars are kept totally clean of personal belongings, with no registration or license plates. The lot has no reserved parking places, so every car has a random location. For a while, you just memorize the make/model/color of each car, and everything's fine. But one day several of the employees buy new cars. How do you then associate each car with each employee? I've got it - you require each one to keep a numbered parking sticker, and they move the sticker when they get a new car. Or, you give everyone a marked, reserved parking place. Or you require each employee to report any car exchanges to you, so you can update your records. If you can solve this one, you can probably solve the other one.

That being said, I've always been impressed with the way that git can understand when I think that a file is the same as some older file (though it does sometimes go wrong): Yeah, git's awesome like that :) It looks at file similarity, though, so if you completely rewrite a file and simultaneously rename/move it, git will lose track of it. And as you say, sometimes it gets things wrong - if you merge a large file into a small one, git will report it as a deletion and rename. (Of course, it doesn't make any difference. It's just a matter of reporting.) Mercurial, if I understand correctly, actually _tracks_ moves (and copies), but git just records a deletion and a creation. My family in fact has a literal grandfather's axe (except that I don't think either of my grandfathers actually owned it, but it's my Dad's old axe) that has had many new handles and a couple of new heads. Bringing it back to computers, we have on our network two computers Stanley and Ollie that have been there ever since we first set up that network. Back then, it was coax cable, 10base2, no routers/switches/etc, and the computers were I think early Pentiums. We installed the database on one of them, and set the other in Dad's office. Today, we have a modern Ethernet setup with modern hardware and cat-5 cable; we still have Stanley with the database and Ollie in the office. The name/identity of the computer is mostly associated with its roles; but those roles can shift too (there was a time when Ollie was the internet gateway, but that's no longer the case). Identity is its own attribute. The problem isn't that identity can't exist. It's that it can't be discovered. That takes external knowledge. Dave's analogy is accurate.

Storing class objects dynamically in an array
Hi,
I'm trying to instantiate a class object repeated times, dynamically for as
many times as are required, storing each class object in a container to later
write out to a database. It kind of looks like what's needed is a
two-dimensional class object, but I can't quite conceptualize how to do that.
A simpler approach might be to just store class objects in a dictionary, using
a reference value (or table row number/ID) as the key.
In the real-world application, I'm parsing row, column values out of a table in
a document which will have not more than about 20 rows, but I can't expect the
document output to leave columns well-ordered. I want to be able to call the
class objects by their respective row number.
A starter example follows, but it's clear that only the last instance of the
class is stored.
I'm not quite finding what I want from online searches, so what recommendations
might Python users make for the best way to do this?
Maybe I need to re-think the approach?
Thanks,
Brian

It'd work better if you actually instantiated Car, instead of just
storing the class object multiple times.
Consider:
usedCarLot[c] = Car(brandList[c], colorList[c], conditionList[c])
usedCarLot[c].Brand = brandList[c]
usedCarLot[c].Color = colorList[c]
usedCarLot[c].Condition = conditionList[c]
Don't do those 3, since you already had to supply the values when
constructing the object.
for k, v in usedCarLot.items():
print k, v.Brand, v.Color, v.Condition

You're repeatedly putting the class itself in the dict and setting its
(the class's) attributes; you're not even using the __init__ method you
defined.
What you should be doing is creating instances of the class:
for c in range(len(brandList)):
print c, brandList[c]

You're repeatedly putting the class itself in the dict and setting its
(the class's) attributes; you're not even using the __init__ method you
defined.
What you should be doing is creating instances of the class:
for c in range(len(brandList)):
print c, brandList[c]
usedCarLot[c] = Car(brandList[c], colorList[c], conditionList[c])
Thanks for the quick reply Dave MRAB. I wasn't even sure it could be done, so
missing the instantiation just completely slipped.
The simplest fix is as follows, but Dave, I'll try to tighten it up a little,
when I turn to the real-world code, following your enumeration example. And
yes, thanks for the reminder (2.7.3). The output is fine -- I just need a
record number and the list of values stored in the class object.
This is the quick fix -- instantiate class Car:
usedCarLot[c] = Car('','','')
It may not, however, be the best, most Pythonic way.
Here's the full implementation. I hope this helps someone else.
Thanks very much for the help!
class Car(object):
def __init__(self, Brand, Color, Condition):
self.Brand = Brand
self.Color = Color
self.Condition = Condition
brandList = ['Ford', 'Toyota', 'Fiat']
colorList = ['Red', 'Green', 'Yellow']
conditionList = ['Excellent', 'Good', 'Needs Help']
#usedCarLot = {0:Car, 1:Car, 2:Car}
usedCarLot = {}
for c in range(0, len(brandList)):
#print c, brandList[c]
usedCarLot[c] = Car('','','')
usedCarLot[c].Brand = brandList[c]
usedCarLot[c].Color = colorList[c]
usedCarLot[c].Condition = conditionList[c]
for k, v in usedCarLot.items():
print k, v.Brand, v.Color, v.Condition

pycache directories
I am doing some OO python3 where I am using multiple dirs/sub-dirs. So everything works fine, however when I run code __pycache__ directories are being created in every directory touched by the execution. Is it possible to set a configuration to be able to create these pycache directories in a specific location? Coming from the Java world - am used to the /src, /bin aspects - so somewhat prefer the 'executables' out of the way. I am using python3 on Ubuntu so wondering if there is some environ setting?

This is much better than having multiple .pyc files in every directory, as in Py2. You should soon learn to ignore them. Is it possible to set a configuration to be able to create these pycache directories in a specific location? No. (I am very sure.) You can however, not have the .pyc files written, but that means recompile with every run.

It could for example be some invisible piece of HTML, or an attribute to some tag.

[issue17006] Warn users about hashing secrets?
New submission from Christian Heimes: Lot's of people still think that something like sha512(secret + message), sha1(password + salt) or even sha1(password) is secure. Except it isn't. Most crypto hash functions like md5, sha1, sha2 family (sha256, sha384, sha512) use a Merkle–Damgård construction [1]. The construction is vulnerable to several attack vectors like length extension attacks. Passwords needs special care, too. I propose we add a warning to the documentation of hashlib. It's not the right place to teach cryptographics but it's a good place to raise attention. The warning should explain that you shouldn't solely hash secrets or messages containing a secret. For messages a MAC algorithm like HMAC should be used. For passwords a key stretching and key derivation function like PBKDF2, bcrypt or scrypt is much more secure.
